BF998
BF998 is Silicon N-channel dual-gate MOS-FETs manufactured by NXP Semiconductors.
FEATURES - Short channel transistor with high forward transfer admittance to input capacitance ratio - Low noise gain controlled amplifier up to 1 GHz. APPLICATIONS - VHF and UHF applications with 12 V supply voltage, such as television tuners and professional munications equipment. DESCRIPTION Depletion type field effect transistor in a plastic microminiature SOT143B or SOT143R package with source and substrate interconnected. The transistors are protected against excessive input voltage surges by integrated back-to-back diodes between gates and source. CAUTION The device is supplied in an antistatic package. The gate-source input must be protected against static discharge during transport or handling. handbook, halfpage 3 d g2 g1 Top view MAM039 s,b Marking code: MOp.
